IntroductionMany materials used at the workplace are classified as hazardous substances such as oven cleaners, glues and solvents. The law requires that safety and health information must be provided to workplaces in the form of Material Safety Data Sheets and labels so that the hazardous substances can be used safely.

This document has been prepared and published by the Commission for Occupational Safety and Health to provide guidance on the provision of information on hazardous substances used at workplaces.

The objective is to ensure that manufacturers, importers, suppliers, self-employed people, employers and employees understand what is required with respect to the supply of Material Safety Data Sheets and how this relates to the safe use of hazardous substances at the workplace.

What is a Material Safety Data Sheet (MSDS)?A Material Safety Data Sheet (MSDS) is a document that provides information about a hazardous substance and how it should be used and how to avoid harm when using it at the workplace.

What the law saysThe Occupational Safety and Health Act 1984 lists a number of specific duties for all employers. Employers must, as far as practicable, provide information, instruction, training and supervision so that employees can perform their work safely and are not exposed to hazards.

People who manufacture, import or supply any substance for use at a workplace must provide sufficient information so that the substance can be used safely.

Part 5 of the Occupational Safety and Health Regulations 1996 (the regulations) requires that information about a hazardous substance must be set out in an MSDS and on the container label.

3

Manufacturers, importers or suppliers of hazardous substances must provide information in an MSDS about the substances such as, the identity of the substance and safe handling, transport, storage and disposal.

Suppliers (except retailers) must provide employers with an MSDS for all hazardous substances obtained by the employer for use at the workplace.

Employers must obtain an MSDS for all hazardous substances obtained for use at the workplace.

Employers must make MSDSs available to all people at the workplace who are potentially exposed to the hazardous substance.

What information must be provided in an MSDS?To comply with the law in Western Australia, an MSDS for a hazardous substance will describe its properties and uses, including:• theidentityofthehazardoussubstance

eg product information to identify the hazardous substance(s) and basic information on uses;

• chemicalandphysicalpropertieseg physical description including description of the mixture or formulation if applicable;

• healthhazardinformationeg health effects from exposure and first aid information;

• precautionsforuseeg correct application and common uses, ventilation requirements, equipment for personal protection and information on flammability; and

• safehandlinginformationeg safe storage in the workplace, safe transporting, dealing with spills and disposal and information for fire fighting and emergency services.

You will find more detail on the information that must be included in an MSDS in appendix one.

4

Who provides MSDSs?

Manufacturers and importers

The person who manufactures or imports a hazardous substance for use at a workplace must:

• prepare an MSDS for the hazardous substance;

• ensure an MSDS is available before the hazardous substance is supplied to the workplace; and

• review and revise MSDS to keep them up-to-date, at least every five years.

Suppliers

The supplier of a hazardous substance for use at a workplace must ensure that a current MSDS for the hazardous substance is provided when a person:

• purchases the hazardous substance from the supplier for the first time;

• purchases the hazardous substance from the supplier at a later time and requests an MSDS; or

• purchases the hazardous substance from a retailer, who originally obtained it from the supplier and requests an MSDS.

5

Employers, main contractors or self-employed people

An employer, main contractor or self-employed person must:

• Be provided with an MSDS either before or on the first occasion that the hazardous substance is supplied to the workplace. If an MSDS is requested, then an MSDS must be provided on the subsequent supply of the hazardous substance to the workplace.

• Consult with all people who might be exposed to the hazardous substance at the workplace about the intention to use the hazardous substance at the workplace and the safest methods of using it.

• Ensure that an MSDS for each hazardous substance is readily available to any person at the workplace who might be exposed to the substance(s).

• Ensure that no alteration is made to an MSDS. The only exception is where the employer is also the importer of the hazardous substance and an overseas MSDS requires alteration to conform with the regulations relating to MSDSs in Western Australia.

When is an MSDS required at the workplace?A current MSDS must be obtained by employers and must be made readily available to employees who may be exposed at the workplace whenever a hazardous substance is used. It is important to ensure that MSDSs are readily available and accessible in the workplace, so that they can be easily located in an emergency, such as fire.

6

When must an MSDS be supplied?There are three instances when an MSDS must be supplied:

• when a hazardous substance is provided to a workplace;

• when a hazardous substance is subsequently purchased and the MSDS is requested; and

• when a potential or existing purchaser makes a request for an MSDS.

When does an MSDS expire?The information in MSDSs must be kept current. MSDSs must be updated by the manufacturer or importer as often as reasonably possible to keep them current and at a minimum of every five years.

The employer should check the dates of all MSDSs and ensure that all MSDSs at the workplace are current.

How should a third party MSDS be used?An MSDS produced by the manufacturer or importer of a hazardous substance must be obtained and used as the main source of information. “Third party MSDSs” which are produced by other parties and not the manufacturer or importer can be used as supplementary information, but should never be relied upon as the sole source of information.

7

Does there need to be any consultation at the workplace about hazardous substances?An employer who intends to use a hazardous substance at the workplace must consult with all employees about the intention to use the hazardous substance at the workplace and the safest methods of using it.

Who must have access to an MSDS? Every person in the workplace who may be exposed to a hazardous substance must have ready access to the current MSDS.

How must an MSDS be kept at the workplace?An employer, main contractor or self-employed person must:

• set up and keep current a register that contains, as a minimum, a list of all the hazardous substances used at the workplace and an MSDS for each hazardous substance used; and

• ensure that the register is readily available to all people who are or who might be exposed to a hazardous substance at the workplace, including emergency service personnel.

An MSDS may be provided electronically if all employees, including shift workers, have access to a computer and provided that all employees are trained on how to use the system.

What are the requirements relating to risk assessments being conducted at the workplace?The regulations state that employers, main contractors and self employed people must:

• identify hazardous substances;

• assess the risk of injury or harm; and

• reduce the risk by:

(a) preventing exposure to the hazardous substance;

(b) means other than personal protective equipment; and

(c) where (a) and (b) are not practicable, by the use of personal protective equipment.

An assessment of the risks from exposure to hazardous substances by employers, main contractors or self-employed people must include a review of the MSDS for each hazardous substance at the workplace.

Certain uses of some hazardous substances are restricted by the regulations with specific safety requirements stated in Schedule 5.2 of the regulations.

If a risk assessment identifies a significant risk of injury or harm occurring as a result of exposure to a hazardous substance at a workplace, then the employer, main contractor or self-employed person must ensure, as far as is practicable, that a report is prepared on the assessment.

Risk assessment reports on hazardous substances must be noted in a register for hazardous substances. The register must be maintained at the workplace and must include an MSDS for each hazardous substance used.

Subsequent risk assessments must be carried out at least every five years and more frequently if it appears that there is an increase in the risk of injury or harm occurring as a result of exposure to any hazardous substance at the workplace.

How can further information on hazardous substances be obtained?Further information can be obtained by:

• contacting the supplier;

• searching the internet as there are a number of sites that may provide information such as:

- www.worksafe.wa.gov.au

- www.safeworkaustralia.gov.au

- www.msdssearch.com

- www.ilpi.com/msds/index.html

- search engines such as www.google.com; or

• by visiting the WorkSafe library and using the MSDS cd-rom.

Note that third party MSDSs should never be relied upon as the main source of information.

How must hazardous substances be identified at the workplace?Hazardous substances used in the workplace must be labelled so they can be clearly identified.

The label must contain basic information about the product and its safe use. More detailed information is available in an MSDS, which employers must make available for every hazardous substance used at the workplace.

In the absence of information, it is safer to assume there is a hazard and precautions taken to avoid skin contact, inhalation or ingestion of the chemical.

In workplaces where many workers do not have English as their first language, employers should ensure that all MSDSs are available in appropriate translations as part of the duty of care to provide safe systems of work.

What are the requirements for providing information and training on hazardous substances?Before hazardous substances are used at the workplace, information and training must be provided on:

• potential health risks and toxic effects associated with hazardous substances;

• control measures to minimise the risks to safety and health;

• correct use of control methods;

• appropriate selection, care and use of personal protective clothing and equipment; and

• the need for, and details of, health surveillance where required.

Frequency of training should be appropriate to the hazardous nature of the substance and the risk associated with its use.

Training must be repeated often enough so that an employee using hazardous substances always uses a safe system of work.

An employer, main contractor or self employed person must ensure that records are kept of all induction and training provided to employees on working with hazardous substances. The training records must include references to each of the topics and details of the information provided including health surveillance where relevant.

What should be done if a person cannot obtain an MSDS from a supplier?If a person at the workplace has purchased, or is intending to purchase, a hazardous substance and the supplier (except retailers) has refused to provide an MSDS, then that person should contact WorkSafe on 1300 307 877. The legislation provides an obligation that an MSDS must be provided and failure to do this may incur a penalty.
